To understand molecular modules related to polyunsaturated fatty acids (PUFA) synthesis and eventually produce PUFA at high efficiency, we developed a protein complex analysis technology in Synechocystis sp. PCC 6803, and applied it to identify possible partner proteins interacting with the key enzymes that catalyze PUFA biosynthesis. We first constructed a recombinant expression of protein of slr1609 encoding the fatty acid activation enzyme, by fusing 3xFLAG tag with the target protein. Then we verified its expression by Western blotting targeting 3xFLAG tag. To maximize purification of Slr1609 protein complex, we optimized the protein expression conditions of Slr1609 in Synechocystis in a 5 L fermenter by monitoring its gene expression using RT-qPCR. The purification of the Slr1609 protein complexes was demonstrated by a Native-PAGE analysis. Finally, LC-MS/MS proteomic analysis allowed identification of the possible partner proteins interacting with Slr1609.

Photosynthetic cyanobacteria possess a series of good properties, such as their abilities to capture solar energy for CO2 fixation, low nutritional requirements for growth, high growth rate, and relatively simple genetic background. Due to the high oil price and increased concern of the global warming in recent years, cyanobacteria have attracted widespread attention because they can serve as an 'autotrophic microbial factory' for producing renewable biofuels and fine chemicals directly from CO2. Particularly, significant progress has been made in applying synthetic biology techniques and strategies to construct and optimize cyanobacteria chassis. In this article, we critically summarized recent advances in developing new methods to optimize cyanobacteria chassis, improving cyanobacteria photosynthetic efficiency, and in constructing cyanobacteria chassis tolerant to products or environmental stresses. In addition, various industrial applications of cyanobacteria chassis are also discussed.

ObjectiveTo investigate the executive functions of the frontal and temporal lobe epilepsy patients.MethodsFifty-five epilepsy patients (twenty-five frontal lobe epilepsy patients and thirty temporal lobe epilepsy patients) and fifty age,gender and education matched healthy controls were evaluated by means of Mini Mental State Examination ( MMSE ).Executive function was assessed using Stroop color words test and trail making test.ResultsMMSE total score of frontal and temporal lobe epilepsy patients were ( 26.02 ± 0.30) and (25.82 ± 0.67 ),respectively.There was significant abnormality between epilepsy patients and the controls (P ＜0.05).Compared with normal control group,FLP group and TLP group took longer time and their score was lower in stroop color words test (P＜0.05).There were significant difference between FLP and TLP on card B and C's reading time,correct number and strcop interference effects (P＜0.05).The epilepsy patients performed significantly worse than the controls in whole trail making test (P＜0.05).The scores indicate that the TLE group outperformed the FLE group on all analysis values (P ＜ 0.05 ).ConclusionThe frontal and temporal lobe epilepsy patients have executive function deficit.The FLE group has prominent deficits in executive functioning.

Objective To explore the relation among the quality of the Paridis polyphylla and different species and growth conditions, and help to provide scientific foundation for introduction and cultivation of Paridis polyphylla.Methods The samples of Paridis polyphylla were collected by different varieties, different growth years, different harvest seasons and different altitude habitats. The content of saponins in Paridis polyphylla was measured by HPLC method according to the Chinese Pharmacopoeia 2015. The chromatographic column was ACQUITY UPLC? HSS T3 (3.0 mm× 100 mm, 1.8μm), the mobile phase was acetonitrile and water (gradient elution), with flow rate of 0.5 ml/min, detection wavelength was 203 nm and column temperature at 35℃.Results Total saponin content ranged from 1.35% to 3.89% among the varieties studied. The content of each components were listed as:Paris polyphylla Smith(PS) >Paris polyphylla Smith var. yunnanensis(Franch.) Hand.-Mazz. (PY) >Paris polyphylla Smith var. chinensis(Franch.) Hara (PC). From 3 to 10 years old of PC, the longer the growth years made the higher the total saponin content. Furthermore, total saponin content of PC increased gradually with the altitudes rising from 400 to 800 meters. The total saponin content of PY harvesting in spring was much higher than that of other seasons.Conclusions The Results showed the importance for introducing and cultivating of Paridis polyphylla.

Objective To investigate the anti-inflammatory effects and mechanism of durian peel extracts (DPE). Methods The in vivo anti-inflammation effects of DPE were examined by carrageenin-induced mice paw edema test and allergic contact dermatitis test induced by 2, 4-DNFB. And the in vitro anti-inflammation effects of DPE were evaluated with methyl thiazolyl tetrazolium ( MTT) assay in RAW 264.7 cell model of inflammation induced by lipopolysaccharide (LPS). Results The results of animal experiments showed that DPE groups could markedly relieve mice paw edema induced by carrageenin ( P<0.01 or P<0.001 compared with blank group). DPE could effectively inhibit the allergic contact dermatitis induced by 2, 4-DNFB in mice, showing good dose-effect relationship. The results of in-vitro test showed that DPE at the given concentrations had no influence on RAW 264.7 cell proliferation. Tumor necrosis factor alpha ( TNF-α) , interleukin 6 ( IL-6) , interleukin 1 beta (IL-1β), nitric oxide (NO) and nuclear factor kappaB (NF-кВ ) were observably inhibited, and anti-inflammatory cytokine IL-10 was enhanced by 25 and 50 mg/L of DPE. Conclusion DPE exert potential anti-inflammation effect, and the mechanism might be related to its inhibition of NF-кВsignal pathway.

Objective To assess the safety and efficacy of stent-assisted coil embolization for acutely ruptured wide-necked intracranial aneurysms. Methods We retrospectively reviewed 192 wide-necked intracranial aneurysms in 178 patients. The efficacy and peri-procedure complications of stent-assisted embolization were compared between rup?ture aneurysms and unrupture aneurysms. Results Stent was successfully implanted in 78 rupture aneurysms and 114 un?rupture aneurysms. There was statistically significant difference between rupture aneurysms and unrupture aneurysms groups in rate of poor prognosis on discharge ( 23.1%vs. 5%,χ2=12.726, P<0.001) but not in the peri-procedure compli?cations rate (14.1%vs. 6.1%,χ2=3.456,P>0.05)nor in the rate of mortality and permanent disability (8.9%vs. 6.1%,χ2=0.475, P>0.05). Angiograms at 14.7 months of follow-up did not reveal any significant difference between rupture aneu?rysms and unrupture aneurysms groups in aneurysm complete occlusion (74.1%vs. 70.6%,χ2=0.197,P>0.05), recana?lization (10.3%vs. 9.4%,χ2=0.034,P>0.05)and in-stent stenosis (3.4%vs. 4.7%,χ2=0.136,P>0.05). Conclusion Stent-assisted coil embolization for acutely rupture wide-necked intracranial aneurysms can prevent recurrence effective?ly and can achieve high complete occlusion rate in long term follow-up. However, its procedure related complications and mortality is higher in rupture aneurysms than in unrupture aneurysms, which indicates that a caution is needed to conduct stent-assisted coil embolization in rupture aneurysms.
